comes from an eatable? An egg of a hen (which can be eaten itself, as well as the hen).
"Or drinks a mouthful." Said R. Jehudah in the name of Samuel: Not a whole mouthful is meant, but so much as would make the cheek bulge out. But we have learned, a mouthful? Nay, it is meant, as a mouthful. The disciples of Zera opposed: Why do they say, about food "the size of a date" (equal for all), and about beverages, "a mouthful" (differing in every person)? Abayi answered: It was certain to the rabbis that food of the size of a date appeases hunger, but only that one's own mouthful of water will quench thirst, not necessarily another's mouthful.
"All kinds of food are reckoned together to the size of the date." Says R. Papa: When one has eaten meat and salt, both are reckoned. And although salt is no food, yet as salt is used with meat, it is also reckoned. Resh Lakish said: The sauce which is upon herbs is reckoned with them. Is this not self-evident? One may say, the sauce is a beverage, and not counted; hence he came to teach, that since it is only made to flavor the herbs, it is reckoned part of the dish. Resh Lakish said again: When one commits an excess in eating on the Day of Atonement, he is not culpable. What is the reason? Because it is written, "They should afflict themselves," and this afflicts him. Said R. Jeremiah in the name of Resh Lakish: A layman who has eaten to excess of the heave-offering must only pay the costs, but not one-fifth more; because it is written [ibid. xxii. 14]: "If a man eat." But eating to excess, to one's hurt, is not called eating.
"Food and beverage are not reckoned together." Who is the Tana who says so? Said R. Hisda, and also Resh Lakish: In this differ the Tanaim, in Tract M'ilah, and our Mishna is according to R. Joshua. R. Johanan says: It may be even according to the rabbis, but there they differ from R. Joshua on the point of defilement, but not from our Mishna, where the question is about appeasing hunger or thirst, for which purposes foods and beverages are not to be reckoned together.
MISHNA: If one has eaten and drunk through forgetfulness, he must bring only one sin-offering. If he has eaten and also done work, he must bring two. If he has eaten food not fit for eating, or drunk liquids not fit for drinking, as brine or fish-lye, he is not guilty.
GEMARA: Resh Lakish said: Why is there no positive command to afflict one's self? It is only said: "Every soul that
